WATER-CIRCULATING APPARATUS.

To all 71171/0111/ t muy concern.-

Beit known that l, LoUIs MARIE GAB RIEL DELAUNAY-BELLEVILLE, engineer', a citizen of the French Republic, residing at Neuillysur-Seine, Department of the Seine, France, and having post-office address 17 Boulevard vented certain new and useful Improvements in Tater-Circulating Apparatus, of which the following is a specification.

This invention has for its object to provide an improved apparatus for producing a circulation of water in the radiator of motor vehicles.

ln the drawing: Figure 1 is a front elevation of an apparatus embodying the features of the invention. Fig. 2 is a transverse ver- In order to demonstrate the advantages of the improved apparatus and its operation, a motor and circulation pump have been shown to the right of the radiator, but it will be understood that the motor and pump may Abo located in different positions wi th relation to the radiator.

The radiator tube A is shown as cylindrical in form, but may be varied in contour and is surrounded by a fixed reservoir B, the tube being completelyT closed and not in communication with lthe reservoir. Two chambers I and 2 are provided in the casing of the radiator A and have con'inumication with the inner port-ions of the apparatus by means of pipes 3 and 1i. A centrifugal )ump C exerts suction at the lower part of' tlie reservoir B through a pipe 5 and forces water into the radiator through the pipe 3, as shown by Fig. I. The radiator is provided with a series of baH'les 6, arranged to extend only partially across the radiator so that circulating spaces will be formed between the ends thereof and the adjacent portion of the casing of the radiator in alternation. The water from the pipe 3 .enters the radiator below the lower bafHe 6 and rises and traverses all the baflies, as indicated by the arrows in Fig. 1, and passes out through the pipe 4 which is connected to the radiator at a point above the u permost baffle, the pipe 4 connecting with t Ie chambers of the motor D. The water passes out through the upper portion of the ,motor D and is conveyed by a pipe 7 communicating with the upper part of the reservoir B, the i Water descending in this reservoir without 1 Patented May 14, 1907.

obstruction into the lower part of said reservoir, where it is again acted upon by the pump C. Connected to the upper part of the reservoir is an exhaust pipe S for liberating the steam from-the water at the top of the reservoir. The radiator has a drain opening 9 formed in thc lower portion thereof and provided with a cock or plug of ordinaryform, this opening being used foremptying the radiator when desired. The reservoir B also has a lower. opening 10, closed by a removable cocl or plug for draining purposes.

The advantages of the apparatus speciiied are as follows: 'The water forced by the pump circulates more rapidly in the radiator than when gravity alone is relied upon, or is more effective than Where a suction pump is used for establishing a circulation.

Owing portion upwardly through the radiator, said radiator is always iilled with Water, and all the surfaces are completely covered. The accelerated and forced circulation of the water due to the connection of the parts hereinbefore noted, produces a more intimate contact of the water with the cooling tubes, so that a greater reduction in the temperature of the water takes place. Furthermore, the friction of the water against the tubular surfaces being greater, any impurities contained in the water have less tendency to adhere to the tubes and the cooling surfaces remain clean for a longer period. The water leaving the chambers of the motor at a considerable temperature may have liberated earthy salts, and the water descending without any obstruction or obstacle to 'the bottom of the reservoir brings with it any salts that it mayl contain, and which will be, to a large extent, deposited and freed from the water, the deposit of these salts taking place in the bottom of the reservoir. This gravitation of the salts or other matter carried by the water, and the disposition thereof at the bottom of the reservoir preserves the cooling surfaces in a clean condition for a longer period, and consequently the efficiency of the cooling surfaces is maintained for a longer time than -if the water passed through the radiator as soon as it left the motor. l

Having thus described the invention, what is claimed, is:

1. The combination with a motor for mo- IOO tor vehicles and a circulation pump7 of a radiator,v a reservoir, a tubular connection between the lower portion of the pump and the bottom of the reservoir, a connection between the upper part of the pump and the lower portion of' the radiator, and tubularoonnections between the upper part .of the motor and the radiator and reservoir respectively.

2. In an apparatus of the class specied, the combinati on with a motor and circulating pump, of a radiator having a series of baffles therein, a reservoir,' and connections between the lower portions of the radiator and reservoir and the pump and between the upper por- LOUIS MARIE GABRIEL DELAUNAY-BELLEVLLE.
